Description

buckle

The present invention relates to a buckle. In particular, the present invention relates to a buckle having an expansion / contraction function.

For example, before and after a meal, or when standing and sitting, you may feel tightness of the belt due to an increase or decrease in waist circumference. If it is too cramped, the belt hole position may be changed to adjust the belt length each time.

In order to eliminate such annoyance, a buckle having an expansion / contraction function has been conventionally proposed as disclosed in, for example, Patent Document 1.
In this buckle, one end portion of the plate-like frame 2 is rotatably disposed at one end portion of the belt 20, and a pin 7 is disposed on the back surface of the other end portion of the frame, and the belt is rotated around the waist of the wearer. In the buckle 1 of the belt to which the belt is mounted by guiding the other end portion to the back surface of the plate-like frame and selectively inserting the pins into the plurality of pin insertion holes 21 formed in the other end portion of the belt, Is slidably disposed in the longitudinal direction of the belt 20 with respect to the plate-like frame 2, and a spring 8 is disposed between the pin 7 and the plate-like frame 2. It is energized in 20 tightening directions.

In the conventional buckle described above, the pin 7 is slidably incorporated inside the plate-like frame 2 and the spring 8 needs to be incorporated inside the frame 2. It is difficult to ensure smooth sliding operation, that is, smooth expansion and contraction operation.
The problem to be solved by the present invention is to provide a buckle capable of simplifying the structure and ensuring a smooth expansion and contraction operation.

In order to solve the above problems, the buckle of the present invention is
A buckle connecting both ends of the belt,
A plate-shaped buckle body,
An elastic member interposed between the end of the buckle body and the end of the belt;
A connecting member that removably connects the end of the elastic member opposite to the buckle body and the end of the belt;
It is characterized by having.
According to this buckle, a plate-shaped buckle body, an elastic member interposed between the end of the buckle main body and the end of the belt, and an end of the elastic member opposite to the buckle main body side Since the buckle with an expansion / contraction function can be configured by the connecting member that removably connects the end of the belt, the structure can be simplified and a smooth expansion / contraction operation can be easily ensured.

In this buckle,
An elastic belt as the elastic member is attached to both ends of the buckle body,
It can be set as the structure provided with the cover which is attached to the surface side of the said buckle main body, and covers a buckle main body and its both ends.
With this configuration, the buckle can be configured to be thin as a whole, the amount of expansion and contraction can be balanced on both sides of the buckle body, and the buckle body and both ends thereof can be covered by the cover. Can be increased.

The disassembled perspective view which shows one Embodiment of the buckle which concerns on this invention. FIG. 2 is a diagram showing the same embodiment connected to a belt, where (a) is a cross-sectional view (a-a cross-sectional view in FIG. (B), (b) is a front view, and (c) is c in FIG. -C end view. In operation | movement explanatory drawing, (a) is a plane sectional view, (b) is a front view.

Hereinafter, embodiments of the buckle according to the present invention will be described with reference to the drawings. In each figure, the same reference numerals are given to the same or corresponding parts.

As shown in FIGS. 1 and 2, the buckle 1 of this embodiment is a buckle that connects both ends B <b> 1 and B <b> 1 of the belt B.
The buckle 1 includes a plate-shaped buckle body 10, an elastic member 20 interposed between an end 11 of the buckle body 10 and an end B 1 of the belt B, and the buckle body 10 side of the elastic member 20. And a connecting member 30 that detachably connects the end 22 on the opposite side to the end B1 of the belt B.

According to this buckle 1, a plate-shaped buckle body 10, an elastic member 20 interposed between an end 11 of the buckle body 10 and an end B 1 of the belt B, and the buckle body of the elastic member 20 Since the buckle with an expansion / contraction function can be configured by the connecting member 30 that removably connects the end portion 22 opposite to the 10 side and the end portion B1 of the belt B, the structure can be simplified and smooth. It becomes easy to ensure expansion and contraction.

This buckle 1 is located in front of the waist or abdomen of a user (not shown), and the end B1 of the belt B and the end 22 of the expansion / contraction member 20 connected to the waist or abdomen are connected by a connecting member 30. It is worn in front of the user's lower back or abdomen. In the figure, the direction indicated by the arrow Fr is the front of the user.

FIG. 3 is a view for explaining the operation of the buckle.
In the figure, a virtual line shows the state of the expansion / contraction member 20 and the connection member 30 before a meal, for example, and the solid line shows the state after a meal.
For example, when the abdominal circumference is relatively small before eating, the stretchable member 20 is in a contracted state (or a state in which the elongation is slight) as shown by the phantom line. As shown by the solid line, the elastic member 20 is extended.
Therefore, a troublesome operation of changing the position of the belt hole to adjust the length of the belt in accordance with the increase / decrease of the abdominal circumference becomes unnecessary.

As the elastic member 20, an appropriate member can be adopted as long as appropriate elasticity and elasticity can be obtained. For example, rubber strings, rubber bands, springs, elastic belts, etc. can be adopted.
In this embodiment, a known elastic belt (for example, a rubber belt) is employed.
By using the elastic belt, the thickness of the entire buckle 1 (thickness in the front-rear direction) can be reduced.

Although the elastic member 20 can be provided only on one side of the buckle body 10, the elastic member 20 is attached to both ends of the buckle body 10 in this embodiment.
If comprised in this way, it will become possible to take the amount of expansion / contraction with good balance on both sides of the buckle body 10.

Although it is not always necessary to provide a cover on the buckle body 10, in this embodiment, a cover 40 that is attached to the surface side (front side) of the buckle body 10 and covers at least the buckle body 10 and both end portions 11 thereof is provided.
